Description

Technical Field

[0001] This utility model relates to the field of laboratory breeding technology, and in particular to a constant temperature and humidity device for laboratory breeding. Background Technology

[0002] Seed breeding involves placing seeds in a cultivation device to germinate them. Seed breeding is the experimental stage of cultivating superior varieties. The first stage is small-scale cultivation, followed by transplanting the cultivated seedlings to experimental fields to cultivate experimental varieties. During seed cultivation, seeds need to be placed in a cultivation bed with a certain temperature and humidity. During the cultivation process, existing technology scientifically calculates the water required for seeds from sowing to germination, and then cultivates and sows regularly and quantitatively. During seed cultivation, excessively high or low temperatures are not conducive to seed growth. At the same time, different seeds have different suitable soil moisture for germination, and excessively high or low humidity is also not conducive to the growth of wheat seedlings. Therefore, we propose a constant temperature and humidity device for laboratory breeding. Utility Model Content

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] like Figure 1-3As shown, this utility model is a constant temperature and humidity device for laboratory breeding, including a water tank 1, a box body 2 above the water tank 1, a heating groove 3 above the box body 2, a partition 4 inside the box body 2, and multiple equidistant support plates 5 on the side of the partition 4 and the box body 2 close to each other. A seedling plate 6 is placed between two support plates 5 on the same horizontal plane, and a seedling trough 7 is opened in the middle of the upper end of the seedling plate 6. Seeds to be bred can be bred through the seedling trough 7 on the seedling plate 6. A humidity sensor 8 is installed on one side wall inside the seedling trough 7 to monitor humidity. Sensor 8 can detect the moisture content of the soil inside the seedling trough 7. A pump body 9 is located at the bottom of the water tank 1. A main guide pipe 10 is located at the output end of the pump body 9. The upper end of the main guide pipe 10 extends between the partition 4 and the box body 2. A branch guide pipe 11 matching the seedling plate 6 is located on the box body 2. The branch guide pipe 11 passes through the partition 4 and connects to the spray plate 12. Multiple atomizing nozzles 13 arranged in a matrix are located below the spray plate 12. When the pump body 9 is working, it can draw water from inside the water tank 1 and distribute it through the main guide pipe 10 and the branch guide pipe 11. Water is conducted through a conduit, allowing it to enter the spray plate 12. The water inside the spray plate 12 is then sprayed through the atomizing nozzles 13, thus regulating the soil moisture. Each of the guide branch pipes 11 is equipped with a solenoid valve, enabling the spray plate 12 to individually regulate the soil moisture inside the seedling trough 7 based on the detection structure of the humidity sensor 8. The heating trough 3 has an air inlet 14 at its upper end. A fan 15 is located below the air inlet 14, and an electric heating element 16 is located below the fan 15. An air guide is located below the electric heating element 16. The air trough 17 has multiple matrix-arranged guide holes 18 on the side near the seedling plate 6. A temperature sensor 19 is provided on one side wall of the box body 2. When the fan 15 is working, the fan 15 drives the airflow, so that the airflow enters the heating tank 3. When the airflow passes through the electric heating tube 16, the electric heating tube 16 can heat the airflow. The heated airflow enters the air trough 17 and is ejected from the guide holes 18. Thus, the hot airflow can achieve the purpose of stabilizing the temperature inside the box body 2. The temperature sensor 19 can detect the temperature inside the box body 2.

[0026] The air inlet 14 is equipped with a filter screen 20, which can filter the airflow entering the heating tank 3.

[0027] The water tank 1 is provided with a water inlet pipe 21 on one side of the upper end. The water inlet pipe 21 is provided with a valve 22. Water can be added into the water tank 1 through the water inlet pipe 21, and the valve 22 can control the opening and closing of the water inlet pipe 21.

[0028] Positioning blocks 23 are provided on both sides of the upper part of the support plate 5. Positioning holes 24 matching the positioning blocks 23 are provided on the seedling board 6. The positioning blocks 23 are inserted into the positioning holes 24. Through the cooperation between the positioning blocks 23 and the positioning holes 24, the placement stability of the seedling board 6 is effectively improved.

[0029] The box body 2 is provided with a box door 25 on the side wall away from the air guide 17. The box door 25 is provided with a pull groove 26, which makes it easier for the box door 25 to open and close.

[0030] One of the boxes 25 is equipped with a control panel 27, and the other box 25 is equipped with a transparent observation window 28. The state of the seeds inside the constant temperature and humidity device can be observed through the transparent observation window 28, and the control panel 27 can control the working state of the constant temperature and humidity device.

[0031] Each of the four corners of the water tank 1 is equipped with brake casters 29, which make it easier for the constant temperature and humidity device to move and be positioned.

[0032] Specifically, in this invention, the seedling trays 7 on the seedling plate 6 can be used for seedling cultivation. When the pump body 9 is working, it can draw water from the water tank 1 and transmit it through the main guide pipe 10 and the branch guide pipes 11, allowing the water to enter the spray plate 12. The water in the spray plate 12 can be sprayed through the atomizing nozzles 13, thereby regulating the humidity of the soil. Each branch guide pipe 11 is equipped with a solenoid valve, allowing the spray plate 12 to individually regulate the humidity of the soil inside the seedling trays 7 according to the detection structure of the humidity sensor 8. The fan 15... During operation, the fan 15 drives the airflow, which enters the heating tank 3. When the airflow passes through the heating tube 16, the heating tube 16 heats the airflow. The heated airflow enters the air guide 17 and is ejected from the guide hole 18. Thus, the hot airflow can achieve the purpose of stabilizing the inside of the box 2. The humidity sensor 8 can detect the humidity of the soil inside the seedling trough 7, and the temperature sensor 19 can detect the temperature inside the box 2. The data detected by the humidity sensor 8 and the temperature sensor 19 can be displayed on the display screen on the control panel 27.
